DSTIKE Deauther Watch X is a cheap wireless hacking tool that runs the ESP8266 Deauther firmware

The DSTIKE Deauther Watch X is a Wi-Fi hacking tool that can be used to test wireless networks, powered by the ESP8266 wireless microcontroller and running the open-source Deauther firmware from SpacehuhnTech. It only works on 2.4GHz networks, since 5GHz Wi-Fi is not supported by the ESP8266. It also features a real-time clock module for displaying the time, like an actual watch. If you are not familiar with the term, a Wi–Fi Deauther is a device that can perform deauth or de-authentication attacks on Wi-Fi networks. It can kick other devices off a Wi-Fi network they are connected to, for learning or other purposes. The Deauther Watch X is the latest product in the DSTIKE Deauther Watch series from Travis Lin and we previously took a look at DSTIKE ESP32 Watch Development Board. The Watch X development board comes in a wristwatch form factor, uses an ESP8266 module instead of […]

PicoVNA 5 software for vector network analyzers supports Windows, Linux, MacOS, and Raspberry Pi

Pico Technology has released PicoVNA 5 control software for their vector network analyzers for Windows x86 64-bit, Mac, Linux x86 64-bit, and Raspberry Pi 3 and greater single board computers, superseding the Windows-only PicoVNA 3 software. As a Ubuntu user, I hate it when some hardware tool forces me to install software on Windows when there’s no Linux alternative, so any company that provides cross-platform tools is making the right move. I’m also not quite sure what a “vector network analyzer” (VNA) is, so I’ll first look into the PicoVNA 106 and PicoVNA 108 6/8.5 GHz VNAs from the company. PicoVNA 106/108 vector network analyzers highlights and specifications: Frequency ranges PicoVNA 106 – 300 kHz to 6 GHz PicoVNA 108 – 300 kHz to 8.5 GHz Up to 5500 dual-port S-parameters per second > 10 000 S11 + S21 per second Quad RX four-receiver architecture Up to 124 dB dynamic […]

Timesys Embedded Board Farm enables remote access to hardware for software development & QA

When you design a new board with an international team working in multiple locations, there may only be a couple of boards available for testing, and that’s mean some members of the team may not have access to the hardware. The same problem can be true for test farms with a larger number of boards. So it would be good to have a solution to remotely access and control the hardware to speed up development. A few years ago we wrote about MuxPi board using NanoPi NEO SBC to enable remote testing of development boards, but now Timesys has come up with a more advanced solution with the Embedded Board Farm (EBF) capable of sharing multiple boards across teams spread around the world. The solution is comprised of three main components besides the target boards: The Master Server integrated with LAVA test automation framework – It handles docker images, firmware/file […]

MuxPi Board Relies on NanoPi NEO to Enable Remote Testing of Development Boards

Product development often occurs in different location over the world, there may be one team in Asia, and another in Europe and the US. At the beginning, the number of working samples for a board may be limited, so the project manager may have to decide who gets the boards since those may not be available to all teams. So it would be great if somehow there was a way to do remote testing of boards, so maybe the team in Asia could setup the testbed, used it during there time, and once they are back home, the US team can take over remotely to carry on their own development work on the hardware. That’s exactly what MuxPi board is all about. The solution provide remote access via the Ethernet port of a NanoPi NEO board, and connects to the DUT (Device under Test) via HDMI, Ethernet, USB and other […]

Realtek RTL8710AF (PADI IoT Stamp) vs Espressif ESP8266 (ESP-07) WiFi RF Performance Comparison

After I posted about PADI IoT Stamp IoT kit based on RTL8710AF ARM Cortex M3 WiSoC yesterday, I was soon asked whether I could compare the RF performance against ESP8266 modules like ESP-12. I don’t have any equipment to do this kind of test, except for some simple test like testing range with WiFi Analyzer app, but I remember Pine64 told me they had some comparison data a little while, and accepted to share their results. The test setup is comprised of Litepint IQ2010 multi-communication connectivity test system and PC software, as well as the device under test (DUT) with PADI IoT Stamp (version with u.FL antenna connector) and ESP-07 ESP8266 module as a u.FL connector is required to connect the test system. They’ve tested 802.11b, 802.11g, and 802.11n, but for IoT projects 802.11b is the most important as usually long range is more important than data rate. Test results […]

Brotli Compression Algorithm Combines High Compression Ratio, and Fast Decompression

After Zopfli, Google has now announced and released Brotli, a new compression algorithm to make the web faster, with a ratio compression similar to LZMA, but a much faster decompression, making it ideal for low power mobile devices. Contrary to Zopfli that is deflate compatible, Brotli is a complete new format, and combines “2nd order context modeling, re-use of entropy codes, larger memory window of past data and joint distribution codes” to achieve higher compression ratios. Google published some benchmark results comparing Brotli to other common algorithms. Since the company aims to make the web faster, the target is to decrease both downloading time (high compression ratio), and rendering time (fast decompression speed), and Brotli with a quality set to 11 is much better than competitor once both parameters are taken into account. As you’d expect the source code can also be pulled from Github. So I gave it a […]

Handbrake 0.10 Supports H.265 and VP8 Video Encoding

HandBrake is an open-source video transcoding tool that I use each time I upload a video on YouTube, simply because it will let me crop the beginning or end of a video as needed, can make web optimized videos, has an easy to use user interface, and greatly reduces the size of the video shot with my camera. HandBrake 0.10 has now been released, and it adds H.265 and VP8 encoding support via respectively x265 v1.4 and linbpx, as well as QuickSync video support, but the latter only in Windows. There are also various other changes include OpenCL accelerated scaling. Handbrake is available for Windows, Mac OS X, and Ubuntu operating systems. It’s part of Ubuntu repository, but if you want the latest version, and support for MPEG-4 (m4v), you’ll need to install it from a PPA:

sudo apt-add-repository ppa:stebbins/handbrake-releases
sudo apt-get update
sudo apt-get install handbrake-gtk

sudo apt-add-repository ppa:stebbins/handbrake-releases

sudo apt-get update

sudo apt-get install handbrake-gtk

I’ve tested with the video I shot yesterday, to see if I […]
